AB Simulation is used to evaluate and validate the behavior and performance of computing systems, in particular the interconnection network in the context of high-performance computing. For the simulation to be performed, the simulator program must be provided with a mechanism that generates network traffic or workload. Although synthetic traffic has been widely used, communication from real applications is a better and more representative workload. With this kind of network workload, the simulations can become slower, especially when simulating Exascale systems.In this paper, we extend the VEF trace framework, originally designed for feeding off-chip networks with MPI traffic, including new functionality related to the on-chip communications and introducing improvements to speed up the simulations. This way, the VEF framework allows to study the behavior of Exascale interconnection networks with realistic traffic and in reasonably short time
